Two weeks after its last update, Apple has updated all four of its developer betas, with fifth releases of iOS 11, macOS 10.13 High Sierra, tvOS 11, and WatchOS 4
macOS 10.13 High Sierra
The macOS High Sierra update, with build number 17A330h, contains a number improvements like Apple File System integration, migration from H.264 to H.265, and Metal 2, alongside other refinements. The previous beta sported build number 17A315i.
A drive with the latest beta installed won't mount, nor can it be selected as a Startup Disk on systems running earlier versions of macOS. However, it does appear when the boot selector is invoked, by holding down the option key on power-up.
The most notable changes in iOS 11 overall are back-end enhancements and an improved voice for Siri, plus Apple Pay and Photos services enhancements. The Do Not Disturb While Driving feature was introduced during the second beta. The fifth beta of iOS 11 has build number 15A5341f, with the previous holding number 15A5327g.
The "Messages in iCloud" feature has been removed in the iOS 11 beta 5 release, and Apple claims that it will ship in a future software update to iOS 11. Users can continue to receive and store messages on each device, and they can continue to backup and restore messages using iCloud Backup.
Release notes for the fifth tvOS beta remain very short, with very few issues noted or changes specified. The previous tvOS build was numbered 15J5333f, and the current has been incremented to 15J5347f.
Apple's watchOS beta 4 has build number 15R5345g. Prior betas delivered the announced "Toy Story" watch faces to testers, and also fixed issues related to haptic feedback, music playback, location-based HomeKit triggers and Siri usability. The previous built was build number 15R5331g.
Registered devices can get the new beta releases through the Software Update feature, while stand-alone images are available through Apple's Developers portal.
The previous update was on July 24.
